IEEE Standards documents are developed within the IEEE Societies and the Standards Coordinating
Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards
through a consensus development process, approved by the American National Standards Institute, which brings
together volunteers representing varied viewpoints and interests to achieve the final product. Volunteers are not
necessarily members of the Institute and serve without compensation. While the IEEE administers the process and
establishes rules to promote fairness in the consensus development process, the IEEE does not independently
evaluate, test, or verify the accuracy of any of the information contained in its standards.
Use of an IEEE Standard is wholly voluntary. The IEEE disclaims liability for any personal injury, property or
other damage, of any nature whatsoever, whether special, indirect, consequential, or compensatory, directly or
indirectly resulting from the publication, use of, or reliance upon this, or any other IEEE Standard document.
The IEEE does not warrant or represent the accuracy or content of the material contained herein, and expressly
disclaims any express or implied warranty, including any implied warranty of merchantability or fitness for a
specific purpose, or that the use of the material contained herein is free from patent infringement. IEEE Standards
documents are supplied “AS IS.”
The existence of an IEEE Standard does not imply that there are no other ways to produce, test, measure,
purchase, market, or provide other goods and services related to the scope of the IEEE Standard. Furthermore, the
viewpoint expressed at the time a standard is approved and issued is subject to change brought about through
developments in the state of the art and comments received from users of the standard. Every IEEE Standard is
subjected to review at least every five years for revision or reaffirmation. When a document is more than five
years old and has not been reaffirmed, it is reasonable to conclude that its contents, although still of some value,
do not wholly reflect the present state of the art. Users are cautioned to check to determine that they have the latest
edition of any IEEE Standard.
In publishing and making this document available, the IEEE is not suggesting or rendering professional or other
services for, or on behalf of, any person or entity. Nor is the IEEE undertaking to perform any duty owed by any
other person or entity to another. Any person utilizing this, and any other IEEE Standards document, should rely
upon the advice of a competent professional in determining the exercise of reasonable care in any given
circumstances.
Interpretations: Occasionally questions may arise regarding the meaning of portions of standards as they relate to
specific applications. When the need for interpretations is brought to the attention of IEEE, the Institute will
initiate action to prepare appropriate responses. Since IEEE Standards represent a consensus of concerned
interests, it is important to ensure that any interpretation has also received the concurrence of a balance of
interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not
able to provide an instant response to interpretation requests except in those cases where the matter has previously
received formal consideration. At lectures, symposia, seminars, or educational courses, an individual presenting
information on IEEE standards shall make it clear that his or her views should be considered the personal views of
that individual rather than the formal position, explanation, or interpretation of the IEEE.
Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership
affiliation with IEEE. Suggestions for changes in documents should be in the form of a proposed change of text,
together with appropriate supporting comments. Comments on standards and requests for interpretations should
be addressed to:

Introduction
This introduction is not part of IEEE P802.15.4g/D5, IEEE Draft Standard for Local and metropolitan area net-
works—Part 15.4: Low-Rate Wireless Personal Area Networks (WPANs)—Amendment 4: Physical Layer Specifi-
cations for Low Data Rate Wireless Smart Metering Utility Networks.
This amendment specifies alternate PHYs in addition to those of IEEE Std 802.15.4-2006. In addition to the
new PHYs, the amendment also defines those MAC modifications needed to support their implementation.
The alternate PHYs support principally outdoor, low data rate, wireless, smart metering utility network
(SUN) applications under multiple regulatory domains. The SUN PHYs are as follows:
— multi-rate and multi-regional frequency shift keying (MR-FSK) PHY
— multi-rate and multi-regional orthogonal frequency division multiplexing (MR-OFDM) PHY
— multi-rate and multi-regional offset quadrature phase-shift keying (MR-O-QPSK) PHY
The SUN PHYs support multiple data rates in bands ranging from 450 MHz to 2450 MHz.

compliance with applicable laws, and these documents may not be construed as doing so.
